SBR5100 为 LRC(乐山无线电)出品的肖特基整流二极管,封装为 TO-277A,适合中大功率整流与开关电源应用。器件在 5A 工作电流下具有较低的正向压降(Vf = 870mV @ 5A),同时提供 100V 的直流反向耐压(Vr),并具备良好的浪涌承受能力(非重复峰值浪涌电流 Ifsm = 150A),适用于对效率与耐受能力有一定要求的电源设计。
TO-277A 封装便于固定与热传导,安装时注意螺丝扭矩、介电垫片与绝缘片的使用以保证机械与电气安全;避免过度弯曲引脚与应力集中。储存与焊接应参照 LRC 的运输与回流/波峰焊指南,注意静电敏感性与长期热应力对器件参数的影响。
型号:SBR5100;品牌:LRC(乐山无线电);封装:TO-277A。若项目对漏电或导通电阻有更严格要求,可考虑同类 100V 级别的低 Vf 肖特基或在更高电流场景下采用并联多只器件或改用同步整流方案。
以上为 SBR5100 的产品概述与设计要点,供工程选型与电路设计参考。如需更详细的电气特性曲线、结壳热阻或典型应用电路,请提供需求,我可进一步整理器件数据与热性能计算示例。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
